Match each statement with the correct term.
Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.
This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Gives variations in species because of overcrossing Meiosis is a bit different because there something called crossing - over happens with the DNA. This crossing over is an exchange of genes. The genes are mixed up - not resulting in a perfect duplic
